speed and velocity becomes equal when a body is moving on a straight road without changing its direction.
The velocity and speed of a moving body become equal when the motion is along a straight line with no change in direction. In such cases, the velocity and speed have the same magnitude.
It doesn't make sense to compare a scalar quantity (such as speed) with a vector quantity (such as velocity). Therefore you can't say that they "are the same" or "are not the same". If the velocity is constrained to be along the x-axis, for example, then specifying the speed (-10 m/s) will also specify the velocity (-10 m/s x-direction).
The magnitude of the velocity is always equal to the speed. But velocity is a vector quantity (has a magnitude and direction) while speed is just a scalar quantity (only magnitude). So velocity and speed are never equal.
Mainly, when the velocity doesn't change. Also, in the case of varying velocity, the instantaneous velocity might, for a brief instant, be equal to the average velocity.
The ratio of velocity to speed of an object is always equal to 1 since velocity and speed are both scalar quantities that denote the rate of an object's motion, with velocity also specifying the direction of motion.
The velocity and speed of a moving body become equal when the motion is along a straight line with no change in direction. In such cases, the velocity and speed have the same magnitude.
It's not. Unless you add a direction to speed it will not become velocity. Since positive and negative are sometimes used to denote direction, absolute value of velocity may equal speed (certain situations)
For the instantaneous value of average velocity, average speed and average velocity are equal.
Speed is equal to the magnitude of velocity when the object is moving in a straight line without changing direction. In other words, if the velocity vector is pointing in the same direction as the motion of the object, then the speed will be equal to the magnitude of the velocity.
Speed doesn't "become" velocity. Velocity is simply speed as a vector, meaning that not only the magnitude is specified (as in the speed), but also the direction.
Yea it is.
This is because speed is defined as the absolute value of velocity - irrespective of the direction of motion.

Speed is equal to the magnitude of velocity almost always. Speed is total distance / total time no matter which way the distance goes. Velocity is the distance from a starting point divided by total time.
Ye.s
The magnitude of the velocity is always equal to the speed. But velocity is a vector quantity (has a magnitude and direction) while speed is just a scalar quantity (only magnitude). So velocity and speed are never equal.
Velocity is a vector, which means it has a direction, but speed isn't. Speed is the absolute value of velocity. Velocity can be negative, meaning that the speed is opposite to the direction that you're calling the positive direction.
